CQMBINED TYPEJWBZTING AND GGIVEPUTENG MACHINE.

5 of Connecticut, have invented certain new and useful Improvements in Combined Type-Writing and Computing Machines, of i which the following is a specification.

This invention relates to computing machines, and is herein illustrated as applied to a combined typewriting and computing machine of the Underwood Hanson type in which, a "series .of jacks are successively moved by a tappet on the typewriter carriage so to act'as denominational selectors of said typewriter carriage.

In said Underwood Hanson machines, as herein. illustrated, each jack is arranged to cause one of-a series of computation racks to I be moved into position where its pin may be .set by means-of the numeral key of the typewriter then depressed. The computation racks and thecomputing mechanism connected thereto'may be of any desired form. A series of these "jacks is shown as arranged in a frame fastened to brackets on the main frame of the typewriter, and a tappet fast on the typewriter carriage is arranged to pass adjacent to said jacks and to raise thenrse'ristint as the typewriter carriage is fed along by the operation of the typewriter :eys. The frame holding these jacks preferably comprises a unitary box member having a rod extending across it, on which red the jacks are pivoted, and inthe front end of said frame there is preferably cut a series of teeth which guide the front ends of said jacks. The rear ends of said jacks are prefe erably guided by a comb which is remorably attached to the rear end of said frame, and the bar of the frame on which said comb rests may be arranged to limit the throw of said jacks. Preferably on the rear end of.

said bar are cut a series of segmental guides, in which rods extending from saidjacks to the computing mechanism proper are arranged to be held, and by-which guides they are guided. A bail, pivoted on the frame holding the jacks, may be arranged to extend around said rods and hold them in position so that each rod will be held under its jack, and said hail may he provided. with a latch. to hold it in position. For limiting Specification of Letters Patent,

the throw downward of said jacks in front. there may be an adjustable cross rod which may be locked at any desired position. The sides of the frame which holds these jacks may extend upward at the top and be slightly undercut so that a cover may slide. in and be held by said undercuts. The box frame prefe ably includes lugs which are arranged to embrace a cross bar fast on the frame of the typewriting machine and through these lugs screws may be passed which serve to lock said frame in any desired position on said cross bar,

()ther features and advantages will hereinafter appear.
